Показать описание

📚 Coming soon: Full networking courses, labs, quizzes, PDFs, and more!

One of the last attributes that is examined as part of the BGP best path algorithm is it prefers the oldest external path. That is, the path that was learned first. This attribute is only valid for external paths, however. In this video, I'll be explaining this particular attribute, and we'll see how it is used to break the tie.

If you want to find out more about the BGP routing protocol, or the method by which attributes are used to determine the best path, take a look at some of my other videos linked below (after the chapter list...)
